If I take for example a depth map who is a scalar image stored in the alpha channel ranged from real units values, like 0 to 1000.
I just can't find an effect to rescale the values for using it in comp, levels on alpha just don't work...
In fact i can with the EXtractoR effect he provide the rescaling feature but my point is:
What is the right workflow with this ?
1. In the footage dialog i can't just use only the alpha channel
2. Why on earth i need to use de Extractor to just leveling my footage
3. How can I clip the result ??? because if i take the result after Extractor and use this as a mask after effect keep some values below 0 and just can't work as a mask, causing AE to just mask the parts from 0 to 1
Many questions i know... I just need some workflow advices
